Abstract
A sanitary napkin includes: a napkin body having a liquid-absorbent layer for absorbing and retaining liquid; and first and second projections each exerting an elastic contractive force between longitudinally opposing front and rear ends to concavely curve the body surface of the napkin body and raise itself from the body surface of the napkin body. The napkin body has an overlap region where the second projections lie on laterally opposite sides of the first projection.
